HTC has been dealt another blow in its ongoing patent battle with Apple. The U.S. International Trade Commission (ITC) ruled Monday that Apple's products don't infringe on patents held by S3 Graphics, a company in the process of being acquired by Taiwan-based HTC, ending the commission's investigation into the matter.
Last month, an ITC judge issued an initial judgment that Apple did not violate four HTC patents related to functions like power management and phone dialing. The Monday ruling concerned S3 patents for texture compression which relate to applications for things like 3D gaming.
HTC is in the process of closing a $300 million deal for S3 Graphics.
An HTC legal representative told The Wall Street Journal that the company was "disappointed" with the ITC ruling but would weigh its options, including an appeal of the decision.
